Comprehensive Trading Performance Summary

The investment history of corporate insiders at MRH provides a unique lens into the internal conviction of the company's leadership. By analyzing SEC Form 4 filings, investors can track how directors and officers are allocating their own capital.

How to Interpret $MRH Trades

Not every insider transaction in MRH is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $MRH shares on the open market. It is crucial to distinguish between scheduled sales (under Rule 10b5-1) and voluntary increases in ownership, which demonstrate management’s true conviction that the stock is undervalued.

Data Source & Accuracy for MRH

Insider activity data for MRH is streamed in real-time directly from the SEC EDGAR system. We analyze raw Form 4 filings, filtering out technical adjustments and complex derivative transactions. This provides a transparent view of how ownership structure is evolving in $MRH, allowing you to follow the capital of those with the most intimate knowledge of the company.

UNDERSTANDING THE DATA

FILING DATE: The date and time when the transaction was reported to the SEC. This is when the public first receives the information.

TRADE DATE: The actual day the insider executed the purchase or sale in the market.

INDUSTRY: The specific market sector the company operates in. Useful for identifying broader institutional capital flows across sectors.

OWNED AFTER: The total number of shares held by the insider following the transaction. This highlights the insider's remaining conviction in the company.

CHANGE %: The percentage increase or decrease of the insider's total position. Large percentage changes often carry more weight than the dollar amount alone.

TRADE TYPES DEFINITIONS

BUY: An open market purchase. Typically indicates an insider's belief that the stock is undervalued or poised for growth.

SELL: An open market sale. While often used for diversification or liquidity, large or unexpected sales can be a warning signal.

OPT+S (OPTION EXERCISE & SALE): This occurs when an insider exercises their stock options and sells them immediately. Often part of a structured compensation plan.
